Luke Morahan is no stranger to Australian Super Rugby derbies, having played in a few for Queensland against NSW.
The flying full-back is set to start another intense rivalry on Sunday when he pulls on the Western Force jumper for the first time against the Waratahs in Sydney.
But Morahan, who joined the Force this season after 46 appearances for the Reds, says it is just another game of rugby.
"It's no different. We're professional athletes, we're going to do our best whenever we run on to the field. No matter where you are you're always going to do that," the one-Test Wallaby said.
"The Force and the Tahs have a little bit of that rivalry, there have been some cracking games over the past few seasons. This is going to be another one of those.
"I'm feeling very comfortable, looking forward to it."
Honours are shared between the two sides in Sydney with two wins apiece and one draw.
The Waratahs are overflowing with Wallabies but Morahan said his side was not worried.
"They've obviously got world-class players throughout the team, forwards and backs. They are going to be a tough task but we're up for it," he said.
Morahan was in great form in the Force trials, scoring one try against the Argentine Pampas and delivering the final pass for three others.
Waratahs coach Michael Cheika has chosen Bernard Foley at fly-half with rival Kurtley Beale at inside centre.
Alofa Alofa will make his debut on the right wing, with Wallabies Israel Folau at full-back, Adam Ashley-Cooper outside centre and Nick Phipps scrum-half.
The starting side features an all-Wallabies front row of Benn Robinson, Tatafu Polota Nau and Paddy Ryan.
·The Force have signed engineering and project services contractor Clough as their "collar partner" for the 2014 season. They have also concluded sponsorship deals with 15 companies for jumpers 1 to 15.
